Abstract

Modified Dumbbell shaped slotted multiband miniaturized antenna with Rectangular, Circular and Elliptical shaped defected ground structures for future mobile communications is presented in this paper. Patch of rectangular shape operating at 2.4 GHz frequency is designed and eighteen slots of rectangular shape with a dimension 2.5mm x 3.5mm is made on outer boundaries of the patch and a modified dumbbell shaped slot is made on middle of the patch. The ground plate is defected with Rectangle, Circle and Elliptical shapes.  The proposed antenna is operated at 6 different N frequency bands of 5G bands including N24 (1.625- 1.660) GHz, N48 (3.550-3.700) GHz, N77 (3.3-4.2) GHz, N70(1.695- 1.710) GHz, N78(3.3-3.8) GHz, and N104(6.425- 7.125) GHz. For rectangular defected ground structure, 4.4dBi gain is obtained. For circular defected ground structure, 4.6dBi gain is obtained. For elliptical defected ground structure, 4.8dBi gain is obtained.  Simulated results shows that designed antenna will be utilized for future mobile communication including GPS, VOLTE, Wi-Fi, and 6 5G bands.
